IMPROVEMENT IN BORING AND EXCAVATING APPARATUS.

Specification forming part of Letters Patent No. 212,218, dated February11, 1879; application filed June 18, 1877.

To all whom it may concern:

Be it known that we, JEROME HAAs and JAMES MANNING, of Stockton, countyof San Joaquin, and State of California, have invented an ImprovedBoring and Excavating Apparatus; and we do hereby declare the followingto be a full, clear, and exact description thereof, reference being hadto the accompanying drawing.

Our invention relates to an improved method and apparatus for borin gwells, excavating, and dredging.

Referring to the accompanying drawing, the figure is a vertical sectionof my apparatus.

Let A represent a tube or cylinder, of any desired diameter and length.The bottom or lower end of this cylinder is open, and its edge may besharpened to facilitate its operation. A short distance above the bottomof the cylinder we divide it by a diaphragm, I), in which is anupward-lifting valve, 0.

At a short distance above the diaphragm b is a solid diaphragm, d, andin the upper part of the cylinder, above this diaphragm, is a weight orhammer, E, which has a length of stroke in the upper part of thecylinder, so that it can be raised and allowed to drop upon thediaphragm d, for sinking it into the earth.

The hammer or weight E is guided in the upper part of the cylinder, andstops f f prevent it from coming entirely out of the cylinder when it ishoisted.

In operation, this apparatus is suspended by a rope from the end of aderrick or other hoisting apparatus, the rope being attached to an eye,h, on the upper end of the weight or hammer. The sharpened lower end ofthe cylinder is then allowed to rest on the ground, and the weight orhammer E is raised and allowed to drop suddenly, and thus, by asuccession of blows, drives the open-ended cylinder into the earth.

The valve 0 allows the air and water to pass above the diaphragm b asthe cylinderis driven into the earth, so that when the lower or earthchamber has been filled the entire cylinder can be hoisted out of thehole or excavation and emptied, the water above the valve serving as apacking to keep the valve tight, and the consequent vacuum above theearth in the cylinder serving to retain the load until it has beenhoisted to the surface.

If the hole or excavation does not cont-ain' a sufficient quantity ofwater we supply it from the surface; and for this purpose we make a holein the diaphragm cl, as represented, so that when water is poured intothe upper end of the cylinder it will pass down and. rest upon thevalve. After the cylinder has been filled the hammer is hoisted upagainst the stops ff, when a further hauling upon the rope hoists theentire cylinder, with its load, out of the hole or excavation.

The hammer might be dispensed with, and the tube filled by dropping itso as to cause it to force itself into the ground.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

The open-ended cylinder A, with its partition I) and upward-liftingvalve 0, and provided with the partition (Z and weight or hammer E,substantially as and for the purpose described.

In witness whereof we have hereunto se our hands and seals.
